PTFE oil seal Advantage: 1.Rubber oil seal lip with spring pressed sharp mouth contact with the shaft lacking a broad prospect of only 0.3-0.5mm, PTFE oil seal lip-free spring-wide power structure, lacking a broad prospect contact with the shaft of 5-7mm, so you can maintain a adequate oil film, but also the eccentric shaft is not sensitive to operating conditions in the radial runout 0.4mm still work properly. 2.PTFE oil seal wall engraved with the threaded shaft turn in the opposite slot, when the shaft rotation will produce an inward thrust, to prevent the outflow of fluid. This thrust is high, leading to shut 1.0MPa (Single-lip), 3MPa (lips) fluid pressure, rubber oil seal is only 0.03MPa 3.Excellent anti-friction PTFE seal sex, especially for oil or less oil-state of the work, even if the re-opening after a long shutdown, it can immediately have a low-friction characteristics of rubber oil seal is only suitable for the work of the oil states. 4. PTFE seals particularly suitable for high-speed rotating applications, the line speeds of up to 30m / s, the maximum line speed nitrile rubber seals 10m/s5, PTFE seals maximum temperature up to 350 , fluoro rubber seals maximum temperature 2005.PTFE seals can seal water, acids, bases, solvents, gas gas, rubber oil seal can only be sealed oil, fats and oils.
